Can't connect sites in MPLS

Have a 4 site MPLS with provider-managed CE routers. Final configuration will be Internet provided to all sites through HQ, along with VoIP at all sites. Currently between HQ and RS1 is a p2p T1.

Was told by provider that all I'll need to do is connect the MPLS router to my core switch which didn't work. For now, just trying to get RS3 and RS4 up on MPLS. When they connect their network to their MPLS router nothing happens. I have the swtich at their location set to the MPLS router as the gateway. If I add an ip route to their network across the HQ MPLS router doesn't do anything.

Attached is my core switch config. I have the MPLS router connected to FE0/3.
